First of all kid, if having sex without a condom is a scare for you then YOU SHOULDN'T BE DOING IT. Yeah I know it feels better or you think you love her, but whatever the case its not worth it! Haven't you seen MTV?! You wanna be like that?! What is it going to take to get through to all you young pleasure seekers that SEX isn't the coolest thing! ESPECIALLY when you should still be out riding go-carts, swimming, playing sport, LIVING! If you two last you will have plenty of time to have SEX. WHATS THE RUSH TO RISK GETTING HER PREGNANT?! Then what will happen? You don't even know and that's why you're here. You are both risking your future and your dreams. If you love her then why would you want to do that to her?
Get her a test in about 3-4weeks from CVS or Walgreens or Wal-Mart (so you can go through the self checkout and save the embarrasment you're going to feel). AND YOU BETTER go in with her to buy it. You had the balls to have SEX without a condom, then you better have the balls to buy that test with her. Imagine if she is pregnant.... You're gna be a young guy and girl looking crazy with a baby on the way.
Goodluck to you and all the kids like you out there, you need it.
